I am being drawn to Islam?

It just seems that the follower of the Holy Koran (Quran) are way more devout than the Followers of the Bible, and yes i have read both books, most of the stuff in both are the same to me, even right down to women covering their heads ( 1 Corinthians 11 from the Holy Bible, and chapter 33 "The Confederates" verse 59 from the Holy Quran). why is that? why are muslims more devoted to their God, their Holy Book, and their religion?
